India's space agency ISRO says that analysis of the Chandrayaan-3 lander data obtained from data from August 23, 2023 to September 03, 2023 shows first-of-its-kind of results on the plasma environment near the Moon’s surface at the Southern higher latitudes, revealing that the electrical environment near the Moon's surface at the South Polar Region is far more active than previously understood.


ISRO reveals electrified Moon environment

ISRO has revealed a groundbreaking discovery: the lunar south pole is electrically active, with Chandrayaan-3 detecting surprising electrical activity in the region. This electrified moon environment, previously unknown, suggests dynamic interactions between the lunar surface and solar radiation, potentially reshaping scientific understanding of the Moon’s geophysics.

A groundbreaking ISRO study reveals strong evidence of water ice hidden beneath the Moon’s polar craters. Using Chandrayaan mission data, scientists found sub-surface ice levels up to eight times higher than surface deposits — a major step toward understanding lunar resources. The discovery could redefine future Moon missions, from habitation plans to fuel generation.

ISRO: India has successfully launched its heaviest-ever communication satellite, CMS-03, using the LVM3 ‘Bahubali’ rocket from the Sriharikota spaceport. Weighing approximately 4,410 kilograms, the satellite is set to bolster the Indian Navy’s network capabilities and enhance communication across defense platforms. This milestone launch demonstrates ISRO’s growing expertise in deploying large payloads into geostationary orbit and strengthens India’s strategic capabilities in space technology.

ISRO is all set for its fourth rocket launch of the year, deploying the CMS-03 (GSAT-7R) satellite for the Indian Navy. The 4,400kg communication satellite — the heaviest ever launched from Indian soil — will enhance naval connectivity and coordination. The LVM3 rocket, with a flawless track record, will complete the mission in just 16 minutes.


ISRO develops indigenous satellite to bolster naval communications

All heavy communication satellites are placed in a geostationary orbit, 36,000 km above the Earth’s equator, from where they provide coverage for about one-third of the Earth. The CMS-03 will be placed above India so that it can provide coverage in the vast maritime region surrounding India.
